Banks has taken issue with the famed producer over their collaboration, “ATM Jam,” and on Tuesday tweeted this: “The reason ATM jam did poorly is because pharell changed his mind about wanting to be associated with me after he had his lite skin comeback.”

Released over the summer, Banks issued the video – which doesn’t feature Williams, who performs the song's hook – in late October. On Friday, Banks told her more than 350,000 Twitter followers that she was removing the song (she once claimed it was originally meant for Beyonce) from her serially delayed debut, “Broke with Expensive Taste.”

But her reference to Williams’ skin complexion was especially disturbing.

Banks has spoken out on colorism before, and once took ASAP Rocky to task, via Twitter, on comments he made about dark skinned women wearing bright colored lipstick. Although she removed the tweet in reference to Pharrell, a similarly terse sentiment toward light skinned men remained on her timeline.

Banks ended her rant with the question “Art or commerce?” – interesting considering she hasn’t taken a break from arrogant cyber bullying to deliver on the hype whipped up from her viral hit "212" and excellent EP “1991.”

If you haven’t listen to “ATM Jam,” which is slinky enough for a mid-day dancebreak, listen here (be warned, there is cursing).
